You’re right that cars can never compete with mass transit in density and bandwidth, and mass transit already operates pretty close to the ideals that I proposed for motor vehicles. If anything it’s an example of why we should implement trains on tracks rather than self driving cars.

But your calculation would be off because there would not be any inefficiencies associated with human driving. Cars would have reduced safe distance, increased max speeds, and would not have to slow down for stops, intersections (assuming walkways are built over intersections for pedestrians), as all cars would be part of the same computer system, and essentially one harmonious unit.

Even if cars are low density and roads are narrow, the increased throughout would be massive.
